sounds like a case for package.provided (like avoiding hwids would be for udev) as you pointed out, this cripples the file detection as well as eg. setting default apps like browser, mail client, terminal i'd have to force USE=mime enabled from Xfce's ebuilds then at very least to prevent breakage, as would several hundred of other ebuilds :/

other option could be to use some kind of "minimal" USE flag. Not sure if there is any USE flag for this kind of force really minimal behavior for "special" setups
i don't think the issue is limited to embedded systems which is why i don't think package.provided is the best answer. iiuc, this makes sense on servers too which have no X at all. having DE envs force it on (like GNOME/KDE/XFCE) seems like a reasonable trade off to minimizing impact on users. i'm not a big fan of USE=minimal in general as it's basically a wild west of "this could literally do anything and varies wildly between packages".

(In reply to Samuli Suominen from comment #7) > actual server software rely upon glib to return correct info Can you give an example?
(In reply to Alexandre Rostovtsev from comment #8) > (In reply to Samuli Suominen from comment #7) > > actual server software rely upon glib to return correct info > > Can you give an example? net-libs/balde relies on it to generate correct content-type headers for static files. It depends explicitly on shared-mime-info though, because there's a configure check for it, as most of the other distros aren't installing this package togheter with glib by default.
(In reply to Samuli Suominen from comment #7) i'm aware it's not X-specific, but it seems like it's largely important to packages which are GUI based. if there are packages that really want the mime logic to be working in glib, then i think it's reasonable to have it depend on glib[mime].
Note that headless servers such a UPnP server with rygel installed would simply fail to be any useful due to rygel not being able to load its plugins if mime support is off. Same for tracker indexing of said server.
(In reply to Gilles Dartiguelongue from comment #11) so update the rygel ebuild to depend on the mime flag. there are other upnp servers that work perfectly fine w/out this (like mediatomb).
