All I am saying is that 'exists()' is simply part of the toolkit that

so why not complete the toolkit in straight variables. The names are a
mess between the three for many reasons and producing a complete new set
of function names has been another call, but there is a simple hole here
in a style of coding which there seems little logical reason NOT to
fill.
Exactly, there’s clearly a gap here. Further, enough people want it that
a few have shown up on this list, which means there are probably many,
many thousands, or even millions, of people out in the wild that want
it. I’m not familiar enough with PHP’s internals to say for sure, but I
suspect it’s not terribly hard to implement (it’s just isset() without
the extra null check). So… why not? Like anything else in the language,
people don’t have to use it if they don’t want to, but it’s good to have
tools. Yes, even tools that can be abused.

I agree. exists() would allow PHP devs to make more secure, cleaner and
lighter code. It fills a gap and would be useful to a lot of devs.
