It seems to me that the system (bricks, outside world etc) is in a nice state of equilibrium right now- no damp problem, basically.
I'd tend to adhere to the "why mess with success" line of thinking on this.
In my block we've had a massive (in some cases comically dreadful) issues in some flats with damp caused by condensation.
It's due to the flats being sealed too effectively- double glazing replacing old steel framed windows, with no trickle vents.
Also, if you are going to possibly extend at a later date why limit what you can do then, now? It's going too be a lot easier to dig down (for example) without there being a fresh concrete floor in the way...
