No, but probably in the minority.
The long and short of it is, you must get ranges in order to enjoy the
power of D algorithms (as per http://goo.gl/dVprVT).
std.{algorithm,range} are commonly mentioned as an attractive asset of
D, and those who get that style of doing things have no trouble applying
such notions to a variety of data, notably including strings. So going
with the attitude "I don't use, know, or care for phobos... I just want
to do this pesky string thing!" is bound to create frustration.
I personally find strings very easy to deal with in D. They might be
easier in Perl or sometimes Python, but at a steep efficiency cost.
Walter has recently written a non-trivial utility that beats the pants
off (3x performance) the equivalent C program that has been highly
scrutinized and honed for literally decades by dozens (hundreds?) of
professionals. Walter's implementations uses ranges and algorithms (a
few standard, many custom) through and through. If all goes well we'll
open-source it. He himself is now an range/algorithm convert, even
though he'd be the first to point the no-nonsense nature of a function
like strrchr. (And btw strrchr is after all a POS because it needs to
scan the string left to right... so lastIndex is faster!)
