My last place also rolled their own feature flag service as their business logic around users/orgs/segments didn't neatly match anything off-the-shelf. It did what it was meant to and worked fine. OTOH we used Datadog for telemetry, which was expensive but made sense since we didn't have enough headcount with the skills to support something self-hosted.

At the end of the day, you just need to make good decisions based on honest analysis of your needs, capabilities, and general context.
