You could publish your findings in a github repository or here on the forums. And then you could create a feature request linking to this repository. And then hope a developer will implement it.
I reverse engineered a BLE protocol myself for tire pressure sensors, and created a custom integration for it, based on the way that other BLE integration are made.
Eventually I want to submit it as an integration for HA, but it’s not perfect yet.
I was not clear. I meant the other half of development. I can capture the communication and reverse engineer it, so someone else can implement it in Home Assistant.
