OTel is so frustrating. If it wasn't shaping to be the clear winner in the space, I wouldn't complain about it as much. But today:

1. Every major vendor is still in some weird alpha/beta support for OTel even after all this time.

2. The performance hit is substantial and makes you question what the point of performance instrumentation is if you need twice as much compute/RAM to run the same workload now.

3. Serverless runtimes pay a heavy penalty for cold starts with OTel.

4. You're basically forced to run both gateway collectors and edge collectors for any realistic usage.

5. You still need to configure destination exporters in unique ways. This leaves you questioning what the value of OTel was.

6. Vendors that go beyond the scope of what OTel covers still need their own bespoke instrumentation. What was the point of any of this then?
