Sounds good, PRs are welcome.

FYI: we discussed this a bit more internally and it turns out that naive extrapolation is not that useful in practice. Users seem more interested in some kind of back-/front-fill approach where first/last value (or even an aggregation of multiple values) is used to fill in the leading/trailing no-data places. But I think this deserves it's own process instead of massively complicating array_interpolate_linear which is quite settled already.

So maybe it's best to close this current ticket for now
