No, no and no. It's its own very specific thing which is like an animal companion but not. D10 HD and full BAB can show you that if nothing else. Anything which applies to a list of things like animal companions, mounts, eidolons etc. has no particular reason it would apply to a homunculus companion.

So its another unsupported dead end class...

It’s not the best alchemist archetype, but the homunculus apparently can benefit from some of the construct improvements.

Wait you can mod it? That... that almost makes it worth it.

You should be able to. Though it’s not an option in PFS, because of the crafting. As always, check with your DM, but it shouldn’t be a problem most of the time.
Even with modding, this isn’t a great alchemist archetype. It bans you from bombs and mutagens and there are barely enough remaining discoveries to take at all and most of those are weak.

Well simulacrum is strong, and so is the tumor familiar, and other the one that let's you reduce penalties for not having the right spells.
As for how strong, the archetype is best as fluff. Unless you are able to mess with all the construct mods/templates and build yourself an army (that may or may not be able to help you make more constructs).

I think the best use of it is a 1 lvl dip to get craft construct with a CL linked to your Alchemy ranks. That way you could craft constructs and play something with more options. Use the Companion as a servant to do non-combat menial tasks.
