indeed. I fully agree, Grav has evaded the attention of many and it feels like a few site-builders (devs, designers, etc) tend to appreciate is core strengths.
The community of the top 3 popular cms-es are currently busy dealing with hardening the codebase (security) and API-ing functionalities (rest / service-based architectures). These days clients are one shy away from asking us to ‘integrate’ one cms to another, pushing content from multiple endpoints.
Personally I hope (and believe) that Grav will be able to stand the test of the upcoming times. And perhaps we can all contribute to its growth soon enough.
