Why having parameter is better? Or, conversely, why having three
functions is so bad? OK, the code would be a bit bigger and the
hashtable would be a bit bigger, but so what? It won't have any
measurable performance effect, so why bother?

Well, there is a standard e.g. for prefixing, but some functions were
born before it was born.
> Examples:
> =========
> isset() vs. is_null()
Isset is not really a function, it's an operator. Same for empty(). is_*
are functions checking variable types (while "set" is not really a type).
> htmlentities() vs html_entity_decode()
Well, maybe it would be better to have all of them have html_* form, but
BC...

I see only one entry.
> quoted_printable_decode() vs quotemeta()
Same as above - BC.

(*) As above - I see no compelling reason why ton of options is better
than ton of functions.

We can't really have parameters for every special case, can we?
> arsort() and asort() should be array_sort() and array_sort_reverse()
Here adding alias seems to be a good idea.

Maybe an alias here too.

It's maybe counterintuitive for you, but not for anybody having any
experience with Unix. Intuition differs.

Because that's how Unix works.

See (*).

OK, but why do you care - isn't it clear what the meaning is?

There is. See CODING_STANDARDS.

We can't remove old names from the manual since then it would not be
possible to understand old code. We could, of course, put notes that
explain which ones is better to use.
If you are interested in it, I would propose to make a list - what you
would like to rename to what, and see how people here feel about it.
