Standardization matters.
“The problem with Arm processors in the desktop (and laptop) space certainly isn’t one of performance – as this latest design by Arm once again shows. No, the real problem is a complete and utter lack of standardisation, with every chip and every device in the Arm space needing dedicated, specific operating system images people need to create, maintain, and update. This isn’t just a Linux or BSD problem, as even Microsoft has had numerous problems with this, despite Windows on Arm only supporting a very small number of Qualcomm processors.”
