So, it is according to you more common that people deal with multiple
external databases on multiple species?

I was under the impression that the average user would be interested
in one or a few external databases, say HGNC and EntrezGene, on one
species.

However, since these seems to be strong feelings about this (especially
among users on the Hinxton campus), we will obviously implement a good
solution for it.

We will, for release 61, add easy to remember alias method names for
get_all_DBEntries() and get_all_DBLinks(), and for release 62 we will
hopefully be able to speed up the catch-all get_all_DBLinks() method.
