I can relate to that and for core this is a good decision. But in Jumbo
we live with lots of external things: Macros like
CL_DEVICE_PREFERRED_VECTOR_WIDTH_CHAR and functions like
clCreateProgramWithBinary(). Not to mention AMD's ADL. We get crazy long
lines without writing code that should be split to more functions.
Actually for OpenCL host code I often just give up and let it span
several lines.

They also decide their name space. We can't.
Also, no matter what you and I say or want, virtually everyone that
contributes to Jumbo DO use 4 or smaller, and I'd rather not complain
too much about it (risking just ending up with less contributions). If
we say 4, we might get away with enforcing it.
