Mind that this refers to PHP license 3.0, version 3.01 slightly changed
the text (essentially s/includes PHP/includes PHP software/) to satisfy
Debian.
I agree that the clauses not necessarily make a lot of sense for most
uses, but mind PECL is not only Siberia but also an incubator. Some
extensions start in PECL and eventually move over to the core
distribution. Keeping the license aligned makes this simpler. (While 99%
of the PECL extensions will never be in a PHP release)

It is tough to write a good legal document when you want to be precise.
Keeping the current form allows a case by case evaluation. From what
I've heard (never done it myself) the PHP Group was quit gracious on
requests. (only case I remember where they requested a rename was
HardnendPHP)

This would require relicensing the ZendEngine first. Currently
ZendEngine uses the ZendEngine license
https://github.com/php/php-src/blob/master/Zend/LICENSE
So PHP has to fulfill the license's requirements and keep that
reference.
In some casual environment I asked them 5 years ago or so whether they
want to relicense the engine which they rejected. Since I didn't really
care I haven't further investigated.

We can't forbid using the name outside the scope of the license within
the license. For that we'd have to use trademark law. Getting
international protection for a three letter trademark requires
recognition and legal power of an organisation like BMW.
