Six Bullseye packages that should be Priority: optional

[Daniel Lewart <lewart3@gmail.com>]

Debian Developers,

Comparing important/required/standard packages between
Buster and Bullseye, I noticed some inconsistencies.

Below are six Bullseye packages that I think should
have Priority: optional, with justifications.

1) Are the justifications valid?

2) If so, should I file one or multiple bugs against:
  * ftp.debian.org
  * src:bind9
  * src:gcc-9
  * src:gcc-10
  * src:mime-support
  * src:readline

Thank you!
