Depends on what you call legacy, I guess. I still use dedicated servers, PHP, Bash, and good ol Perl.
Heck, I even "downgraded" as far as the cool kids are concerned, and went from Ubuntu Server to openSUSE recently.
If Rails + Postgres counts as legacy then yes, my usual MVP stack.
Yes - fun story:
End of last year I participated in an investor meeting where our tech stack was criticized for being "too legacy", when in fact (in the security industry) it's pretty damn critical to provide robustness and integrity over ${LATEST_SHINY_JS_FRAMEWORK}.
It's probably good that relationship didn't end up working.
