Not exactly the same thing - I believe that ticket is referring to just the
WKB format handling?
I can make a ticket for measure handling by the overlay operations if there
isn't one already.

Hi,
GEOS operations do not preserve M, but sometimes preserve Z. You can try
ST_SwapOrdinates(ST_Intersection(ST_SwapOrdinates(geom, 'zm'),...), 'zm').

1. What values do you want to assign to intersections of lines and
polygons (if not on vertices)?
2. You can try with ST_DumpPoints, but this will "recreate" only those
segments that are completely within intersecting polygon:
with
l as ( -- linestringm
select st_makeline(st_makepointm(1,
