I respect that the PHP maintainers recognize that it is not enough to accept a working JIT implementation - they have to understand and maintain it. Speed is one thing, but long term maintenance is more important.

But at the very least, this exercise will ensure that DynAsm will be actively used by a few people. So even if this PHP JIT effort fails, the underlying JIT technology will be more widely understood and hopefully better documented for other projects.

True, however I would argue that having an IR in general makes the code easier to understand and maintain. Especially if you add more optimizations.
