Using higher spell slots for non-upcast spells?

Curious: Do DMs you know allow players to use higher spell slots to cast spells that don't upcast technically?

I'm thinking of spells that have a fixed effect, like Lesser Restoration, Misty Step, etc. when you're out of 2nd level spell slots. You're burning a stronger resource to do so.

It's explicitly allowed:

When you cast a spell, you expend a slot of that spell’s level or higher,

If there's no upcasting benefit, the only reason to do it is because you're out of lower-level slots. (Including being a warlock.)

The rules explicitly state this is allowed.  Notably, even if there is not a specific, tangible effect, the spell is still cast at a higher level.  Most of the time that will not be relevant to the spells you listed, but there are going to be edge cases where it might come up.  For example, under the 2014 rules of Counterspell, the Counterspell looks at the level of the spell cast, so these spells would be harder to counter with a higher level spell slot.

Even in the new rules there are still cases where this matters, such as Leomund's Tiny Hut blocking spells of level 3 or lower.

Being a multiclassed warlock is another less common reason. It might be better to spend a higher level slot that you get back on a short rest rather than a lower level one that you only get back on a long rest.

Oh cool, already in the rules, thanks all!

And yeah, that was the reason I cited.
