I've run my desktop system with a number of modules (8 in total) for a
while without any problems.

Kernel modules introduce a number of possible failure paths and an avenue
for malicious code to be loaded. As such, some might determine that the
flexibility isn't worth it for their production online systems. If uptime
and stability is that big a concern, you probably shouldn't be running
CURRENT in the first place. ;)
