My guess would be that it was seen as one of PHP's big strength that variables
don't just leak into other contexts but that it has to be done explicitly.
Now with arrow functions both the benefit of auto-capturing is bigger compared
to the actual function 'body', it normally only spans a line or two and (for me
personally) the absence of {} also kind of make the leakage fit my mental model
more easily.
For these reasons I think I lean towards -1 for both

<https://wiki.php.net/rfc/short-functions> and
https://wiki.php.net/rfc/auto-capture-closure
<https://wiki.php.net/rfc/auto-capture-closure> as they add more syntax without
(IMHO) a huge benefit.
You might be able to convince me otherwise though ;-)
