The biggest issue with ElasticSearch (that was the only issue raised during all that time) is that it takes a lot of RAM and it's an extra dependency. So it was made completely optional, not everyone wants to deal with that.

It (quite obviously) only operates on data that was in the PostgreSQL database anyway. It took 78 lines of code (mostly one file) to add the indexing (which is part of the reason it was chosen - ease of integration).
