"Business reasons" ever come up as a rationale? RSA was patent encumbered until
Sept. 2000. To include RSA, NAI would of had to have given RSADSI a license to
freely redistribute PGP - not exactly in their (NAI's) best interests.
Patent issues were still around when RFC 2440 was being drafted, hence RSA and
IDEA being deprecated.
Maybe reading some history of modern cryptography would help.
See this FAQ from circa 1999 (Dated but historically accurate):

Cause it's covered by 7? There are so many possible combination of key/subkey
capabilities that listing all of then would make the menu far too long.

Relying on the 'highly effective" Security via Obscurity model, huh?
There's no guarantee that your key won't end up on a keyserver nor is there one
that your "private" email address won't leak into the public,
