Yes, but its more complicated. In my case I have slides with a number of include files, some have not changed since 2006 (just checked), one does not want to maintain slides with same ancient version of typst, and then possibly have many floating around.

For me, they need to promise full backwards compatibility.

That's a valid point: if you don't want a language that makes breaking changes (so you can always compile old files with the latest version), it's not the right time to use typst. It's just moving too fast now. It's currently at version 0.11. Come back when they release 1.0.
