$ hg log -h | grep -- -T
 -T --template TEMPLATE   display with template
$ hg status -h | grep -- -T
<no output>

All the functionality that used to be available with --style got unified into --
template and -T was added as a shorthand everywhere we used to have --template.
-T also exists for lots of other commands, but because it's marked
"(experimental)", it doesn't show up in help.
