currently not but i can make that an option (fallback)

for that i need to change a load command

hm, i suppose one can add the parsing of /BTEX .. /ETEX to the lexer and 
then intercept it but it's not built in (formatted comment might make 
sense)

no

yes (i use it myself)

no, they are not obsolete (the scite lexers are often also syntax 
checkers so they are more strict) ... the pret files are more or less 
working in the same way (they date from before scite got that kind of 
lexers)
