Required dependencies

[norkunas]

Could we make symfony/form as an optional dep? For example I don't use forms in app but it's installed because only this package requires them.

We can make symfony/form optional. Usually, it is required by the project itself.

I'm thinking, what does it involve:

• bump the major version
• update composer.json, obviously
• add instructions on how to install in readme
• maybe tweaking tests

Is there anything else required?

I think that'd enough for this change.

Usually, it is required by the project itself.

I just use validator constraint, so the form is not needed :)
