The idea and implementation seems good to me, extremely happy to have more warning/error checking for map, so thank you for this. @kparzysz is likely the best reviewer for final approval as he's our semantic level guru :-)

As an aside, if this doesn't already cover the case, would it be feasible/make sense to have a similar warning for the declare target (I think it's specific to "TO/ENTER" if I remember correctly) case that falls into a similar category, where an ALWAYS needs to be emitted for any data updates to actually occur?
