Is there maybe a slightly more intuitive syntax? I'm not really worried
about the break of pattern being just a single byte, but it seems to me
something like <offset>+<pattern> or so would be easier to understand?

iw wowlan enable disconnect patterns 14+88:8E

It would also be more obviously wrong to an old iw version -- it would
reject this, while it would accept "14 88:8E" as two patterns.
