Transpilation platforms. There's a lot of new programming languages being written, but few people want to use a programming language without many libraries. One solution to this is to host the new language on an existing platform/library ecosystem, e.g. JVM, BEAM, Lua, C, but this requires choosing a platform and tying the language to that platform (and accepting the design choices of that platform's major implementations, e.g. in some cases, the platform implementation may have slow startup time, which makes it hard to use your new language for quick scripting from the commandline). Instead, one could imagine a programming language platform designed to transpile the new language to multiple underlying platforms. Like LLVM IR, this transpilation platform could be a nexus that supports many different frontends and many different backends. Such a transpilation platform would make it easier for new languages to be useful sooner.
