"I Only Trusted My Channel Abstraction After Plugging In the Third Provider"

There is a quiet rule a lot of us follow: don't abstract until the third use case. One integration is a script. Two integrations is copy-paste with a shared helper.

Telegram was the first channel. Feishu followed a few weeks later. Both went fine.
