Usually I'd agree. However (and I've just checked this) all file
versions are identical.

Since this is an Argonaut Games format, I checked the version of all the
ASF files in their most recent games. The only two versions found were
1.2 and 2.1, both of which are already supported.

Because this format is looong-dead, I see no harm in ignoring file
version (especially if the muxer allows specifying arbitrary versions).

I shall update the commit message accordingly.

$ for i in ~/Desktop/staging/asf_music/*/*; do ./asfdump.py $i | jq ._version; done | sort -u
"1.2"
"2.1"
