write a program that uses SMF(E)WTM to write type 199 records and they will
end up in your SMF datasets and/or logstream (subject to any IEFU8x exit).
What a well-behaved program *should* do, apparently (although this does not
seem to be well-documented) and apparently what ACF2 and every IBM product
do is query SMFRTEST to determine whether the shop wants its record type,

This is news to me. I can't speak to the validity without writing
my own program, but on the surface doesn't seem to agree with the
description for SMFRTEST in the SMF manual. Pay attention to the
wording in the last sentence.
5.8 SMFRTEST -- Testing record recording
The SMFRTEST macro allows you to determine if a particular type, or subtype,
of a record is being recorded. Issue this macro before collecting data for a
particular record or subtype to avoid the overhead of data collection
if it is not written.
The wording is based on the assumption that the test will be done
before an attempt to add the record to the SMF dataset and that the
record will thus not be submitted if the result indicates that the
record is not to be recorded. This does NOT however say that a
submission of such a record will be rejected by SMF. The wording
needs to be updated to mention testing before submitting since there
is a difference between the records being blocked by SMF itself and
the submitters not submitting due to the macro call results.
There is a subtle difference in the significance of that sentence.
This is that it is worded as "Do not bother to do the collection
since there WILL [not the correct (if submitters check before
submitting) SHOULD] not be any records".
