Because you probably have never considered what havoc would be caused by 
changing in mid-stream anything about the processing of identifiers and 
similar strings that are not text, but unambiguous references to 
domains, files or other resources.

(You can make some changes when you create a new domain and set rules 
for it for the first time, but that's about it).

Good luck banning SS in "all Germans".

You probably did not consider the fact that German written in 
Switzerland only uses ss and SS and therefore banning SS would be more 
than confusing. It would needless compromise a well accepted local 
orthography.

German written in Germany has undergone a transition, and as partially 
as a result of / but mostly in parallel to that transition, we see a 
secondary shift in capitalization away from a typewriter / telegraph 
inspired fallback to a more natural way of writing where all letters 
have a case pair and casing is reversible.

  The same cannot be said for Swiss German. There's not been a similar 
transition, which would have needed to start with lower case usage. As 
long as the Swiss don't use ß, I can't see them banning "SS".
