Not sure but my guess is because they aren't a good fit for many languages. If you need a task runner then often languages will have a built in option or there are better alternatives than Make. If you need a build system then Make isn't a good fit for a lot of modern languages.

I’ve been using earthly a lot lately and its general value prop is simple: it turns out that if Buildkit is your primary build tool that Make targets can almost always be represented as OCI image layers. The killer feature IMO is that its syntax is familiar enough to end users of both Make and Dockerfiles that engineers tend to be willing to onboard to it. A lot of these other solutions that use proprietary DSL’s struggle to cover every use case, and the implementations in turing complete typical language SDK approach often forces you into analysis paralysis if there is no existing pattern.
