**Better:** *"I find it hard to read this code as there many nested if statements, can you make it more

readable? By encapsulating some of it's details or maybe adding some comments to explain the overall logic."* -

* ``This code doesn't comply with Symfony's CS rules. Please see [...] for details``.

* ``Symfony 3 still uses PHP 5 and doesn't allow the usage scalar type-hints.``.

* ``I think the code is less readable now`` - careful here, be sure explain why you think

* We tried that in the past (link to the relevant PR) but we needed to revert it for XXX reason.

* That change would introduce too many merge conflicts when merging up Symfony branches.

In the past we've always rejected changes like this.

* I profiled this change and it hurts performance significantly (if you don't profile, it's an opinion, so we can ignore)

* Code doesn't match Symfony's CS rules (e.g. use ``[]`` instead of ``array()``)

* We only provide integration with very popular projects (e.g. we integrate Bootstrap but not your own CSS framework)

* This would require adding lots of code and making lots of changes for a feature that doesn't look so important.

That could hurt maintaining in the future.
