+1. IMHO the current behavior is wrong. "replace" should always replace the element, no exceptions. (Zope 2 has the same bug, I just checked.)

You can certainly disagree with this behavior, but it is not a bug.

See http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AdvZPT.stx
for example, which states that default is "A special value that doesn't
change anything when used in tal:replace, tal:content, or
tal:attributes. It leaves the template text in place."

But see also the "Omitting Tags" section for opposite examples:

<b tal:omit-tag=""><i>this</i> stays</b>

Renders to:

<i>this</i> stays

At this level of usage, tal:omit-tag operates almost like tal:replace="default".

Now in my Z3 sandbox 'tal:replace="value"' is just a syntactic sugar for 'tal:content="value" tal:omit-tag=""' (I guess this is only the way to work around the "automatic msgid's translation" issue) so I've found the bug.
