Unfortunately AFAIK the author of that script where that choice was made
has never been known to post here. However, the main advantage of static
linking for GROMACS is slightly faster execution when calling out to
dependent libraries, and I'd say that's not important enough for bioconda
for it to want to build it that way.

The questions and build scripts can be seen here:

I'll comment more there.
