allows control of this pins behind e.g. a I2C IO expander

Thanks for your contribution.

I assume you have actual hardware with an IO expander. Is it part of a bigger device?

Thanks for merging. Yes I have, it's a custom DIY project with IO-expander (NRST-pin) and E32-900M30S-module that needs two inputs to switch between RX and TX. The weak-approach allows me to get rid of ugly patches.
