Add-ons are only ever installed either as a required dependency, or as an optional dependency where the existing version is too low, or when the user initiates the install of an add-on.
They're never installed "on demand" or anything like that.
The optional dependency is to specify that the add-on will make use of it if it's there, but won't freak out if it isn't. i.e. it's up to the user to install that optional dependency, rather than the add-on author.

Yup, that's true - there's specific code for installing plugins, forgot about that.

Thanks. I see the difference now, just didn't want to try using it myself one day and not get the results I expected. Sounds like the use of this would really be an edge case in most situations.
