One of the broken clients (not in this place particularly, but in a few
others) is Google Chrome.
Sometimes it takes year to convince devs to do something about that, even
if the issue is obvious. Here is an example:
And if something isn't working in browser-webserver combination then this
is usually us who will be blamed for. Because people need their services
working in the first place. As a result, you can see such commits:
I agree with your arguments about the positive side in enforcing strict
validation. On the other hand, the main goal is to keep our users setups
working with any clients. The world isn't perfect and neither us, nor our
users can fix it.
As the 1.11 branch is going to be stable soon, it's a good idea to postpone
any changes that explicitly affect interoperability (at least till 1.13).
