Yes, it's just a matter of finding time.

I'll have to check the code for this.  A brief scan through
the code doesn't indicate anywhere that caching is being
disabled for pagelist.

However, this is incorrect, as we cannot cache pagelist
output if any of the pages in the pagelist have read
protection (and $EnablePageListProtect is set).  So, I'll
need to update that.

The bottom line answer will be that pagelist output will
be cacheable unless:
 - $EnablePageListProtect is set and one or more of the
   pages has read protection
 - the pagelist is using the request=1 option
 - the resulting pagelist template invokes any of
   the "non-cacheable" items I listed in my previous message
 - anything else I happen to think of :-)

Note that "HTML caching" is different from "pagelist caching".
HTML caching caches the output of entire pages, while
pagelist caching simply speeds up the output of the
(:pagelist:) command.
