Has anyone ever used a universal x-plug 120/240 receptacle? It seems you can plug in a NEMA 5-15, 5-20, 6-15, or 6-20 cord cap into it.

That's usually very specific to go to those devices ends, just my opinion.
I do usually install 20 Amp rated receptacles with side-ways slit in neutral.
Residential and light commerical you'll never see a need , oh 90% + most of the time...
Now in manufacturing and production it'd be a whole different game, those needs might well exist!
What do you want to do with all those ?

was just wondering what they would/could be used for, I thought there was a code issue with being able to plug a 110 volt cord cap into a 220 volt receptacle.

Here we go, back to the future- again!
The 'X Plug" is nothing but a depression-era plug design, with a ground prong added. I would maintain that such a plug could only be used as a replacement for an existing such receptacle. I'd look real careful at the listing and labeling.
It's not plain in the picture, but the devices USUALLY have one slot larger, to accept the neutral plug blade. That is, the device is probably "polarized."
The pattern comes from a time where there were no conventions as to plug patterns, and many appliances had plugs where the two blades were in iine with each other ( "- -" rather than " l l " ).
It may surprise some, but the NEMA patterns we're familiar with did not get defined until the mid-60's; some parts of 'the chart' were not settled until the early 70's.
Personally, I think the idea of having a receptacle that will take any plug, without regard to the electrical needs of the appliance, is a really bad idea.

Thank you for your reply. The receptacle is being reintroduced by medicinal grower suppliers here in Ca.;
