There was a problem hiding this comment.
Trying to keep compatibility with lowest symfony/validator versions for this bridge, as the code isn't impacted, only the tests fixtures are.
Same for the Form component.

…rings which defaults to `true` in 4.4 but will trigger a deprecation if not set explicitly in order to make the default `false` in 5.0.

which defaults to
truein 4.4 but will trigger a deprecation if not set explicitlyin order to make the default
falsein 5.0.While it could be solved now thanks to #29641 by using both
@Length(min=1)&@NotBlank(allowNull=true)constraints,as expressed in #27876 (comment) and following comments, the
@Length(min=1)behavior doesn't match our expectations when reading it: it feels logical to invalidate empty strings, but it actually doesn't.Hence the proposal of making the behavior of rejecting empty strings the default in 5.0.
In my opinion, the flag could even be removed later.
