Hello Maurice

Can you provide more details on what the difficulties are and when relief should 
be expected for this?

When you say "supply chain issues" for C++17, I am thinking that those 
customers are buying compilers in a DVD in a box and that is stuck in a 
container still sailing from China. That obviously can't be the case.

My proposal was that C++20 wouldn't be required until March 2024 for non-LTS 
users. The first of your LTS to require it would be the one from October 2024, 
and it wouldn't become the oldest LTS until 3 years after 6.5 (March 2026).
