Debian Policy 10.4 (Files/Scripts) notes that:

  When scripts are installed into a directory in the system PATH, the
  script name should not include an extension such as .sh or .pl that
  denotes the scripting language currently used to implement it.

sg3-utils includes /usr/bin/rescan-scsi-bus.sh, which violates that
recommendation in the policy.

Note however, that the package "scsitools" already includes a command
named "rescan-scsi-bus" under /sbin/rescan-scsi-bus, which would
conflict with sg3-utils if rescan-scsi-bus.sh would be renamed to
rescan-scsi-bus.  Besides being quite confusing, should one happen to
install both packages, it turns out that both of these scripts seem to
be derived from a common ancestor.  Maybe a solution can be found
between the package maintainers such that Debian ends up with only one
version of that script.

Yes. But rescan-scsi-bug is a very widely known tool. And on every
distribution, it is known as, along with the .sh extension.

From what I've checked so far, that is not from the same upstream as
sg3-utils.
