phobos breakage... why?

[Adam D. Ruppe]

I was just playing with the beta, and got this among the
sea of errors:

arsd/cgi.d(898): Error: function std.algorithm.indexOf!("a == 
b",ubyte[],string).indexOf is deprecated


Why was that taken out? If you ask me, the root cause of D's
perceived stability problem has little to do with bugs. It
is 95% phobos devs removing functionality at random. Why do we
keep doing this?
