Try it. It changes nothing. The only effect is that if you look into
/proc/self/status you'll see (as root):

[...]
CapInh: fffffeff
CapPrm: fffffeff
CapEff: fffffeff

(the 'e' indicates that root doesn't have the CAP_SETPCAP capability).

And as a normal user:

[...]
CapInh: fffffeff
CapPrm: 00000000
CapEff: 00000000
