yep, and the accessories belt swap can be done in 10 minutes flat thanks to honda's design 
Everyone that has had the original water pump for for over 120K, check the bottom of the pump housing where the 'leak' hole is. I can almost guarantee you already have a very small leak there
but its too small to make a difference. In any case, I'd replace it before it gets to the point that it does. Plus its cheap and easy to install a new one.

my guess is that leak issues are a gasket issue, and the mechanics of the water pump itself will be fine.
i purchased only the water pump gasket and will replace that soon (not sure if there's a leak, but i'm losing coolant slowly and can't find the leak anywhere else).
am i wasting my time, should i replace the entire water pump?

If your water pump is leaking, the chances its the gasket, and not the seal are extremely low.
I often say be careful your actions to avoid an outcome don't inadvertently cause it. Replacing the water pump as preventative maintenance risks not bleeding all the air out, thereby causing sudden, engine destroying overheat. These cars are difficult to bleed.
Since a leaking pump gives plenty of warning, and because they rarely go bad (as billman attests, not to mention the guy with near 400k miles hasn't replaced his yet), it seems like a risk with no real benefit.
Sometimes our zeal to give extra special care to our precious possessions is misplaced, and counterproductive.
Replace it when it starts showing signs its going bad.

i've replaced every coolant part except the water pump, and I tested the oil (blackstone labs oil sample) to make sure the lost coolant wasn't going into the cylinders.
so literally that leaves only one part that hasn't been changed to account for the coolant loss...the water pump. i've changed the radiator, radiator cap, overflow tank, upper lower hoses, heater hoses, coolant hoses that run around the intake manifold, thermostat. only part i didn't change is the water pump.
now i'm just overthinking whether to replace just the water pump gasket or the entire water pump.
i note there's also a gasket in between the thermostat housing and the block. not going there yet though.

2 things damage pumps, cavitation, and wear from using non approved coolant. And as long as you are using the right coolant and aren't full of air pockets none of that should be an issue. 184k on original water pump here.
On Toyotas, their water pumps fail constantly due to cavitation destroying the pump bearing seal.
