To me leaving split completely out of the name is going to prompt questions of
"why did my rig go into split mode".
It actually does a frequency split just like all splits do. It's just that
WSJT-X then adjusts the audio to maintain the reception offset during transmit
instead of you having to tell the other person you shifted. It's another use
for split mode....not a non-split mode thing. Can't say I know any other
software doing it but it's still really a split frequency operation. Split has
always meant split carrier...just that the audio typically shifts with it.

I'd like to weigh in on the "what to call it" discussion. Not that I have
anything really better, but since we already have a well understood "split
mode", called this a split confuses one function with another. Can we say
something like "Audio Purity Offset"?
I have not used it before I'm willing to give it a try. I let you know what my
Apache 100D thinks about it.

The WSJT-X User Guide includes the following text in Section 4.2:
"Split Operation: Significant advantages result from using Split mode (separate
VFOs for Rx and Tx) if your radio supports it. If it does not, WSJT-X can
emulate such behavior. Either method will result in a cleaner transmitted
signal, by keeping the Tx audio always in the range 1500 to
2000 Hz so that audio harmonics cannot pass through the Tx sideband filter.
Select Rig to use the radio’s Split mode, or Fake It to have WSJT-X adjust the
VFO frequency as needed, when T/R switching occurs.
Choose None if you do not wish to use split operation."
I'm not sure what we could write that would be any more clear.
I have no idea what you mean by "it’s not standardized across the platform".

Why do you need any "solution"? Solution to what problem? For FT8, or for any
other mode??
