They have done remakes, but they have done them sparingly. Usually after a long period of time has passed as well. (Over a decade for the UCS Xwing and rumored UCS snowspeeder remake, a bit less than a decade for the Sandcrawler) And in many cases, they updated models with new building techniques and minifigs to reflect the display quality that fans have come to expect nowadays.
If they remake too often, and without any meaningful improvements (a la Winter Village Toy Shop) that will absolutely bring down secondary market prices. 10179 is the premier example of Lego's collectibility and remaking it so soon (it's only been gone, what, 5 or 6 years now?) is damaging to the perceived value of Lego as long term investment, to some degree.
I do think they'll remake it at some point, because they could charge a fortune for it and still sell tons of them. Remakes are inevitable but they should be very careful about how they do it and how often they do it.
