Yep, when I saw the stock situation, I order some 82uH parts, and tested
them, in excess of the recommended load. Worked great. I had already tested
the RLB9014-101, way back when, but routinely ordered the RLB9012 part due
to the extra safety margin.

Thanks for your answer :)
As I read you, I could use either RLB0914-101 or RLB9012-082 instead?
I just checked and I can get the RLB0914-101 from my supplier of choice!

The coil issued with the kit is a Bourns RLB9012-101. All major
distributors (Mouser, Digikey, ...) are currently out of stock, and back
ordered to May. That coil is a tad overkill for what the supply is rated to
output. The RLB0914-101 will also work to more than the posted maximum
specs. So
You're right. The current rating for an inductor is an "up to" value, as it
states the maximum current you can pass through that part without
saturating the ferrite core. A saturated inductor in a boost converter will
heat up and the converter won't reach designated voltage.
Btw. I've read
Thanks for your answer.
All right, it does make sense, my concern was with the rest of the circuit
only being designed for 1.4A. But I guess the key here is that it's "up to
1.4A", which I will never reach, even thought the rating is higher.

A higher-current-rated inductor of the same uH value and same type will be
fine - inductor #4 is likely as good as the original...
