Technically the entityService is not still there because localized entries are not working anymore with the removal of the localization-Array?!
Technically you mark something as deprecated but change the behaviour and make it unusable: that’s not deprecated.
Yes.
I would assume that Strapi as product in its current stage (quite long beta, v4 as “we fixed some shit that we’ve messed up”-version) will only get new features, changes regarding security, performance, … .
And not: “Hey, let’s think about how we can change existing core functionalities - the community surely will appreciate that!”.
@Paul_Brats Is there a specific date/month currently planned for the release of v5?
