Considering that portage failed to apply your patch, specifically for
the reason that the patch specified to remove the below line[1] which
was *not present* in the copy of configure.ac portage uses, it is
probably safe to say that the ebuild doesn't make use of this feature
anyway. As you stated originally, it isn't used unless explicitly
enabled.

Now, I did some more nosing around in the Status Tray panel plugin
settings. The settings I have show two sections, one for "Status
Notifiers" and one for "Systray Icons" and the things I use on the
daily are actually split between these two sections. It seems Telegram,
nheko and Steam are "Status Notifiers" whereas Signal and Deluge are
"Systray Icons". I have no idea if these distinctions are semantically
meaningful, or if they are relevant to the discussion at hand, but I
figured I would add it in case someone else goes spelunking in the
future.

Regardless, I've stood down from my initial knee-jerk panic at losing a
relied-upon feature, at least for now.
