Move the transformers into an independant bundle

[shavounet]

Description

Is it a good idea ?

Transformers are a big part of the process bundle, and could be independent with a easier access to them.

@tonongregory what is your take on it? it seems to be annoying to manage?

[VincentChalnot]

For your information I already kind a did that on a personal project for test purposes and it makes sense but the it breaks backward compatibility completely because it involves moving all transformer in a new namespace.

For example I have a bundle that handles object mapping/conversion a bit like the Serializer but more advanced, Transformers are really helpful and I'm not using anything else from the ProcessBundle.

Hey @shavounet are you still using the ProcessBundle ?

Yep, 100% a major BC break, but worth it in some usecase (aka calling transformers without the full process bundle).

Nope, it didn't gain traction here, and now we're switching away from PHP
