Yes, and we concluded that we'd rather not pursue it at this point. Quoting from https://github.com/tpde2/tpde/issues/6#issuecomment-3389235973:

Upstreaming would either require us to split TPDE and TPDE-LLVM (requires vendoring TPDE in LLVM, causes too much development friction) or to include TPDE entirely in the monorepo (requires all TPDE users to pull in the LLVM monorepo, huge dependency, also causes development friction). As I said earlier, I consider TPDE to be primarily a research project and the LLVM monorepo is not a good space for research. We don't deeply depend on LLVM internals, so there're no significant technical benefits either.
