It seems that there are no consensus about this feature so...

I don't see any serious objections to it except comments from people
that seem not really understand what this feature is about and complain
about "bad code" which has nothing to do with the actual feature
proposed. I am all for consensus, but I have very hard time accepting it
as a valid objection, sorry.
I agree that argument is absurd... Even Freemarker, which is rather
unforgiving with missing values (see
http://freemarker.org/docs/app_faq.html#faq_picky_about_missing_vars ),
provides this in the form unsafe_expr!default_expr. It's not about writing
sloppy code, it's precisely the opposite -- identifying clearly and
succinctly the regions where missing values are expected.
