Although we might state a requirement, or it is "strongly suggested",
that if the environment doesn't allow you to find out the Scheme
procedure throwing an exception, the status object it throws must
include it.

My concept is something like this:

required by SRFI 198: 'set
required by e.g. SRFI 170: ??, but fewer than the current required
"strongly suggested" by SRFI 198: 'message, 'foreign-interface, ??
"strongly suggested" by e.g. SRFI 170: ??
"nice to have, and we have a Schemeregistry standard": 'heritage

The last is to e.g. tell a user of R7RS-large into which SRFI 170 has
been assimilated where he might look to find historical information.

For example, the SRFI doc of course does not explain why all of the
particular decisions were made about its API.  But someone wondering
why so many but not all SRFI 170 file system procedures take only a
string filename can search the archived discussion and discover the
reason was to lessen the burden on implementors using the 80/20
Pareto Principle as a guiding principle.
