There were reports of higher than normal writes on M1 based macs not long ago.

They cannot truly boot externally- even when you do boot external there is an initial dependency on the SSD, so if it fails you have an expensive brick.

Older models where not soldered on the motherboard.

They've been soldering them on since the 2016 MBP[0]. I thought you were referring to the reports of unusually high writes on M1 macs, thus shortening the life of SSDs[1].

Yes they were, just look at the teardown for a model from the year before: https://9to5mac.com/2019/07/12/2019-13-macbook-pro-teardown/

Unless by older you mean over 5 years old that is incorrect.
