If that were the case, then surely it would be C'D's?

Or C.D.s, because abbreviations are sometimes denoted by a full stop.

To be fair, language is a fluid, ever changing thing, and the rules are continually changing.

My boss (of the elder generation) uses a hyphen in to-day and to-morrow. My dictionary says that's 'archaic' usage. I must point this out to him!

Also, someone was discussing semicolons earlier. I think it's also possible to use them to separate phrases in lists, rather like one would separate a list of single words using commas. But the poor old semicolon is underused in my opinion. I frequently see sentences which should either be split into two separate sentences, or at the very least have a semicolon in the middle.
