The lgpl3+ is by itself not a complete license, it is structured as a
few exceptions under conditions to the gpl.  The lgpl3 even asks you to
include both a copy of the GPL3 and the LGPL3 license text:

https://git.sr.ht/~technomancy/fnlfmt/tree/main/item/LICENSE#L91

   b) Accompany the Combined Work with a copy of the GNU GPL and this
      license document.

Strictly speaking that's only for ‘Combined works’, and I don't expect
any trouble in practice.  However, it would be nice to do things
properly.  Would you be up to asking upstream to include a copy of the
GPL as well (which upstream isn't doing currently)?
