Upgrade command does not remove #[ApiSubresource]

[BeyerJC]

API Platform version(s) affected: 2.7.1

Description
Maybe this is intened but after running the upgrade command, a new ApiResource was added in my related entity class but the #[ApiSubresource] attribute was not removed.

How to reproduce
Create two related entities, add #[ApiSubresource] attribute and run the upgrade command.

Possible Solution
If this is not intended the command should remove the attribute after creating the new GetCollection.

Even by using php-cs-fixer after? Maybe we forgot something even though it's not a big deal as they won't be processed in 3.0 (or legacy flag to false).

No, php-cs-fixer did not remove the attribute. It did not cause any trouble besides my IDE complaining :-)
