Because 25519 and 448 are the IETF standard curves.  More curves are a
hassle for interoperability.

NIST and Brainpool have been with us for 10 years and are still required
by some policy requirements.

GnuPG 2.3.0: new ECC curves

[karel-v_g--- via Gnupg-users]

Hello! 
The list of additions and changes to GnuPG 2.3 is quite impressive. Thanks for 
all the work on GnuPG.
Just out of curiosity one question: why did you "only" add curve x448 from the 
SafeCurves project and not also E-521? For NIST and Brainpool the available 
curves >500bits are also already supported.
Cheers Karel
