Then those extensions should expose the required information. These are bugs
then.
More importantly, it does not only contain information about
extensions,
or which extensions are loaded and how ( I am aware of the problems of
using this kind of information as authoritative, I still say something
is better than nothing, see every 404 page in all modern browsers, why
not provide suggestions, even if they are wrong ).
Path information I figure could be useful while setting up software, so
The paths set during configure time don't have to match those where things are
installed. Especially admins might prefer to use symlinked paths for
configuration and users might be misled.
could many other configure time options, for example if more than one
SAPI was built at configure time, you might advise the use of the most
suitable SAPI for your software,
SAPIs might be built individually. Having them enabled during configure time
doesn't mean they are enabled or accessible by the user.
you might generate an ini file and
tell
the user where to put it (scandir), you might have the abnormal path to
php-config or other things distributed with php and installed in a
non-standard path (/opt/php-nts in example output).
configure options often won't tell-
There's a bunch of useful stuff in the configure command ... not just
extensions loaded ...
Yes and a lot of wrong information.

A combination of ENV, ini, phpversion and phpconfopt options should
allow you to make much more informed decisions or do nothing at all,
there is not a reasonable means to acquire this information, nor is it
reasonable to suggest that we modify every single bundled extension in
order to expose their configuration options, additional constants and
maybe add new functions/methods.
I keep using the words could, might, maybe, *on purpose*, I am aware
that the configuration time options may not match runtime parameters, I
don't think it falls to us to provide the business logic, so it doesn't
really matter that the setup may be completely different, it may be the
same, or similar. It may be vital information, it may also be completely
irrelevant, exposing it provides more flexibility than doing nothing at all.
