I went to the source at Frasca and they confirmed that while the 141 can be
used for all of the purposes listed on the website (including instrument
currency which is what I was doing), it should be logged only as simulator
time, and not as total time.

From Frasca (who manufactures everything from FTDs to Level D sims):
"Usually people log it as Simulator / FTD(Flight Training Device) time.
While the time does count toward your flight time training requirement
for instrument for example, airlines, 8710's etc. usually want you to
break them out so it is easier to just leave them separate in a
simulator column and not include them in your total time. The only time
I would put a simulator flight in Total time column would be in a level
D full flight simulator as the airlines use."

Looks like the original responder was right, I stand corrected.
