The second variant looks more verbose and more ugly to me. Also 
wouldn't it require an extra level of indentation if properly 
formatted?

Dropping support for the @trusted function attribute even after 
some deprecation period would be a rather annoying compatibility 
breaking change. That's a high price for something that is just 
cosmetics.

Also how do you imagine writing future code that is compatible 
with both the most recent versions of D compilers and also with 
GDC 12 (frontend version 2.100)? GDC 12 is included in Ubuntu 
22.04 LTS and will be relevant for a very long time.
