They were first deprecated on Mar 01, 2018:
https://dlang.org/changelog/2.079.0.html#hexstrings

And removed in 2.086, so it's probably unlikely that any 
maintained code is using them.

Deprecated in 2.097, maybe a good candidate to obsolete instead.

cent and ucent are already an error as of 2.100. Were they even 
implemented?

Changing the syntax just for an obsolete feature would send the 
wrong message. People rarely use octal so it doesn't need to be 
in the language, library is enough. The C syntax is indeed bug 
prone - leading zero.
