This seems as a quite bold statement given the fact that most authors of
Web content will be too lazy to markup sentences.

Yes, for translation it is sometimes important to do segmentation to
sentences properly. However as semantics of HTML elements is known in
advance there usually no problem with this. For some rare ambiguous
cases you can use ITS markup (which can be applied to HTML as well) to
set segmentation boundaries
(http://www.w3.org/TR/its20/#elements-within-text).

Well if automatic spacing algorithms fail (which is not that often as
you describe, at least in my experience) you can always fix missing
space by inserting en- or em-space character manually which seems as
much less barrier then putting element around each sentence.
