Not only for your project but for everyone
Yeah this is not only a project for me, it's also a project for the community

One sentence: you get more flexibility (that's what bossanova808 wrote

2. What are the hardware environments you feel will benefit from this the best?
3. How do you plan on replacing the AMP that is part of your receiver?
4. It's my understanding that the sound processing on a receiver is much better than those used in sound cards (especially THX enabled receivers), have you done any testing on this?
1. Hard to say before it is not finish.
2. & 3. I plan to use a dedicated AMP without any signal processing capabilities and do all the signal processing stuff at the Kodi side.
4. It depends on the used sound card or DAC, no at the moment I didn't tested any hardware. The AudioDSP feature isn't finished and I don't have enough money to buy some test hardware. But I think we can get a great music experience with a very good DAC or sound card.

Because not everyone has a AV-Receiver. Another use case for e.g. could be a car or if you don't have enough space for a full AV-Receiver. On the other hand the room correction algorithms are all closed source and no one except the company, which developed the algorithms knows the inner workings. If the software part in Kodi for audio processing is more powerful you can spend more money for e.g. on better speaker or an AMP.
Also the mic from audassey seems very cheap to me and not every AV-Receiver supports other microphones and not every AV-Receiver supports to upload correction files for a microphone.
Don't understand me wrong I really like my Denon X2000 and it's room correction system. I use it every evening and I'm quite happy with my environment, but I really like to develop audio signal processing stuff and prove if I can beat the commercial systems
I don't know if I can beat them, but if know one tries we don't know what is possible.

I'd say there is plenty of coolness potential here
That's a perfection description and I can't say it better. Thanks.
Room correction is only one use case what is possible with the addon adsp.xconvolver. It's a efficient convolution engine and you can load filters to achieve this features (similiar like BruteFIR

That's another great use case. Use old AMPs with new signal processing algorithms

2. If you have an expensive receiver you will probably want to continue using your receiver for this feature.
3. If "like OP" you are interested in getting rid of your receiver this feature helps bridge the gap between the features you would loose by dumping your receiver. (I still believe that current mid range and up receivers provide a wealth of benefits to sound processing that Kodi is unlikely to fully replace) but everyone has a different use case, and this feature will certainly help a lot of people.
2. Or you can test which one sounds better
3. I think no because AudioDSP is very young and we don't have enough Add-ons. I don't know if you are fimiliar with C/C++ code, but if you can read it. You should look into it and I think you would be impressed and how powerfull ActiveAE is. I think not all commercial AV-Receivers have this powerful engine. With AudioDSP the gap would be closed at one day.

2. Will this feature be able to detect if a speakers polarity is incorrect?
1. & 2. Hard to say at the moment and I don't know which features would be integrated during GSoC. But the first version can measure your room impulse response and can correct it. The two features which you mentioned can be integrated after GSoC.
