Has there been any push/interest in allowing unlisted (standard ASTM A53)
schedule 7 steel pipe to be allowed by code in place of the listed "flow"
piping options?

Keep in mind, NFPA 13 states piping or tubing that meets Table 7.3.1.1 is
acceptable. Listing is NOT required.
*NFPA 13 - 2019: 7.3.1.1 Pipe or tube shall meet or exceed one of the
standards in Table 7.3.1.1 or be in accordance with 7.3.3.*
Thus, as long as any piping or tubing material complie
ts are any different from plain ASTM
A53 pipes.

Matt,
Having seen many cases of failed sch. 7 pipe over the past 10+ years I would
tell anyone willing to listen to stay far, far away from it. Pipe schedule is
the most basic form of corrosion/leak

The original question is actually very interesting. You mentioned Schedule 7
pipe and I bet pretty much everyone that read that immediately thought of
listed flow pipe. Until there is a requirement to standardize the ID's there
will not be an appetite to put "Schedule 7" in the
