Yes.
I have a hose heater, like that in the lower hose of my 1985 300SD.
Works for me to -40F...

Cost was $32.00 at a generic part store...

The glue on pan heater addition = it would start at -80F.

at -80 F I ain't goin outside

For those trips to the south pole right?

Yea right.... I don't like going outside when it is below 40F.

I can imagine what happens to the fuel at that temperature? You would have to use a lot of additives (kerosene) or something.

Unlikely it would start at -80F....since the fuel would be a solid!

What if you had one on the fuel tank too, like the Russian GaZ trucks used in Siberia?

The real issue seems to be: if you install it, will it work? And the answer appears to be yes, i.e. the product is reliable enough.

I would favor the hose heater both for generic availability and ease of installation. Plus less likely to be affected by high snow drifts scraping the bottom of the oil pan under some trying circumstances.
