I use a lot of php-cli scripts and I've never seen the need. Without having
hard data to back this up, I am pretty sure that this applies to nearly all
php-cli scripts.

Obviously we should. Whether people will use it is pretty much the most
important aspect for deciding whether or not something should be added.
Even a trivial addition is a loose for the project if nobody is going to
use it. And this is no trivial addition. This seems to be quite a bit
system dependent and uses some odd methods like overwriting argv memory.
And on that note, it also has to copy the argv data if I got that right,
which is something it has to do always and not just when people are
actually using the feature ;)

I'm not saying I'm against this feature. I'd just really appreciate it if
we could drop the good old "it doesn't matter if people are going to use
it" non-arguments and instead provide a bit more info for people like me,
who are not in the process-title-hacking business. I.e. what this is needed
for an why this is needed in core. E.g. what Arvid mentioned, that this is
useful when you are running many PHP-based daemons and want to distinguish
them. That's the kind of stuff I'd like to see in the RFC.

Regarding core/non-core. People mentioned that this is not implementable as
an extension. That can be either solved by putting it into core or by
adding the necessary API hook ;) [I'm not arguing which variant is better,
just saying that not being implementable with current core does not mean
that we can't make it implementable :)]

Thanks,
Nikita
