[sdiy] VCO Linear FM input - DC or AC coupled?

hey everyone,
i noticed some vco schematics have a dc blocking cap on the linear fm cv
input and some are directly coupled.

is there any advantage to either? AC coupled seems to block out the
possibility of really slow FM modulation with an LFO - or at least makes
the response not intuitive.. so I can't really see the point.
