yes

Here is some examples (talk-de) what some people think to be accurately
tagged as tunnel whilst it will obfuscate the database if we would.

http://de.wikipedia.org/wiki/Br%C3%BCckenrasthaus_Frankenwald

this one is not rendered correctly if just using layer=1 on the building due
to mapnik rules (they always render ways above buildings and do not respect
layers for these cases).

this one produces the "obstacle-problem" you would not have with a real
tunnel.

cheers,
Martin
