I agree.

I still think that ${foo} is more shell-like, and that's a good thing. 
In sh-style shells, $(foo) means "execute foo and grab its output, but 
${foo_withWEIRDname} means get the variable foo_withWEIRDname.  bash 
introduced the parentheses thing as an alternative to backticks.  The same 
braces syntax rules apply for gettext variable replacement.  PHP, God help 
us, uses a similar syntax too.  I personally have not seen a $(thing) 
variable substitution syntax outside of the bash "run thing and get its 
stdout" that I mentioned above.

I feel fairly strongly that ${foo} is better, but overall this is by no 
means a big deal.  So hopefully I can convince you to use braces, but if 
not, then we'll still be friends and I'll still use your software and 
everything.
