A number of these issues, while they might be showing heavily from users with M1 Macs are actually on going issues with a range of Macs.

The Bluetooth issue is one I have had on both Macs I have owned. A 2013 MacBook Pro and a 2015 MacBook Pro. Both have issues with dropping Bluetooth connections when hot spotting with Bluetooth, with Air Drop and with an external mouse. In most cases I just found work arounds.

I specifically made a point to buy the 2015 MacBook Pro in 2018 (nearly the end of its sales cycle) specifically because of the lack of diversity of ports on newer MacBook models. It is the one great dislike I have with MacBooks now only one port type for everything. Eventually I will have to live with it when I next need to upgrade, but that will be put off as long as possible.

If these are the biggest concerns with this chip, it is a phenomenal position for Apple. Just consider the bugs in the operating systems with every new release. Maybe the hardware team could teach the software team some things.
