Why are the exec* functions deprecated in std.process?

[Andrei Alexandrescu]

I am using the new std.process and am disappointed with it.

There is no convenient function to replace the running process with a 
new one. There used to be the exec() family of functions, which 
conveniently use string[] for arguments etc., but now the doc says:

============
These functions are scheduled for deprecation. Please use spawnShell 
instead (or, alternatively, the homonymous C functions declared in 
std.c.process.)
============

The problems are:

1. spawnShell does NOT do the same thing as exec*. The former waits for 
the spawned process and then continues the calling process. The latter 
_replaces_ the running process with the new process.

2. The homonym (not homonymous btw) functions in std.c.process use in 
char*, not string, which makes them unpleasant to use.

So... what to do here?
