OK, thanks for this information.
It's unfortunate that the source code for Amiga LhA is not free.
The m68k version can unpack it.
Yep. The Amiga LhA decided to be compatible with UNIX LhA instead of old Amiga Archives.

Regarding point 1: the majority of archives would be 'Amiga' ones.
When you expect a UNIX archive, wouldn't you have a higher number of CRCs (and double decompress operations) than when expecting an Amiga archive?
Nope. 99% of Amiga LhA archives have been created with LhA that never generates archives which could show the issue. The Amiga LhA compression algorithm has been tuned to avoid that.
Amiga LhA archives that show the issue are actually quite rare, so the performance impact should be limited.
