in principle this makes sense, but in practice it doesn't.
the list in sourceforge does not contain any feedback from the dev team, no way for someone to know if their request was accepted, rejected or even considered, no place for advocacy, so the team has no way of knowing if this is a single user's itch or is it something that many would find useful, there is no feedback (although a feedback mechanism does exist, it doesn't look like it's being used).
in short, the sourceforge feature request list looks dead. one gets the sense that it would be just as effective to write the request on a piece of paper, put it in a bottle and toss it in the ocean.
the header at the top of the list reads:
Thanks for all your submissions. The list of features for phpBB 3.0.x is now being frozen.
Please note we do not take a look at this tracker very often - so please bear with us if your entry goes uncommented. Once we have the time we will go through the list.
At this stage it is recommended to only post if you were redirected to this tracker by a phpbb.com team member.
the message itself is not dated, so for all we know it was written 3 years ago and no team member have visited since.
iow: since this is the only (known) place to put a feature request, i think it's fair to say that there is no feature request option for phpbb at this time.
btw: the oldest request on sourceforge's phpbb-feature-request list, from 2007-08-02 has the following comment:

the moment, please read the description. This is for tracking "verified"
requests only. We will open up "open" requests at a later stage.
there is an active and live "mod request" forum on phpbb.com, but some things only make sense if they are included in the core product, and do not make sense as mods, so in a sense it's a pity that no feature request/discussion/advocacy exists.
oh well...
