But people love Python :) Make's indentation is mainly hated because of 
the fact that it's the special invisible indentation of the tab 
character that's important.

Discussions of indentation vs {} for marking blocks can go on for ever, 
some like python style and some like perl

Most of the decisions were made because of the desire to keep things as 
simple as possible for the implementation, and to require as little 
translation in going from xsltxt to xsl and vice versa as possible. 
Certainly other choices could have been made but they would have 
complicated the lexer beyond what I wanted to deal with. For my purposes 
what I have works reasonable well, perhaps I'll revisit the syntax in 
the future and make some of the changes you suggest.

I'll probably look at xslt 2.0 in the future.
