Related Products code inside Spree core

[mrbrdo]

I'm not sure if you are aware but there is quite a bit of code related to this gem:
https://github.com/spree-contrib/spree_related_products

inside spree core, for example:
https://github.com/spree/spree/blob/main/core/app/helpers/spree/products_helper.rb#L122

And also in spree_legacy_frontend.

As far as I can see the gem was not updated for over 1 year and it seems it's not compatible with Spree 4.5 at the moment. Although I did a few updates to fix that (spree-contrib/spree_related_products#200)

Anyway, do you think the code from core (and ideally from legacy frontend too) should be moved into the gem? Or is there a reason this code would be in spree code? The db migrations are in the gem and not in spree core, so it makes little sense to me.
