It's funny how irritated I get with other non-Smalltalk editing systems that do not (seem to, anyway) allow me to get text enclosed or unenclosed easily. Just plain text.

I was a bit annoyed by how autoEnclose (and by extension autoIndent)
were in effect for even the most basic of TextMorphs,

autoEnclose is not Smalltalk-specific.  In all languages, including
plain English, when you use an opening parenthesis, 9 times out of 10,
there's gonna be a closing one, so autoEnclose is convenient pretty
much everywhere.  The exceptions are a tiny minority.  Nevertheless,
these are independently adjustable preferences which you can turn off
if it doesn't suit you and they won't bother you even in
SmalltalkEditors.
