Perhaps there is a chance to further relicense the code to LGPLv2.1 *or later*? As things stand now, GPLv3 projects are not able to use the code; invoking the exception on code that is normally part of the operating system seems a bit of a stretch.

You do know that you can relicense LGPL-2.1 code to GPL-2+?

"You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices."

The LGPL only specifies a minimum version of the GPL to relicense to, not a maximum. Thus, there is no problem at all.

Bad typo. :) I meant LGPLv3 projects.

Note that the blanket "or later" relicensing only applies to LGPLv2. It was removed from LGPLv3.

It's not that bad though, as you can still combine the two as a GPL-3 work. And you can link to the LGPL-2.1 licensed library in any LGPL-3 work as well, without causing the conversion to GPL-3.
