In other words, we can introduce a pattern-type later and make the current pattern-type the default. Thanks for looking to the future.

I think the nearest planned change to ref storage is [1], which is still optimized for prefix matching. Longer term, maybe some day we'll want a secondary index that supports infix matching, or maybe we'll never need it. :) Sincerely, Jonathan [1] https://public-inbox.org/git/CAJo=hJsZcAM9sipdVr7TMD-FD2V2W6_pvMQ791EGCDsDkQ033w@xxxxxxxxxxxxxx/#t
