I think too many HM's is a legitimate complaint, since it honestly is bothersome having to give up potential spots for good moves, just to make sure you can actually progress in the games, or having to replace a Pokemon with an HM slave. However, like most, I don't agree with complaining about the amount of water. It's part of what makes Hoenn what it is, and it ties well into the story. The story is basically the battle between the sea and land, and they tie this well together with how the region is built, by making a large part of the journey take place on the water. And while I may personally not have liked it very much in R/S, as long as the encounter rates have been made smaller, or the prices for repels reduced, I have nothing against it, and it definitely wouldn't be a faithful remake if they decided to remove some of the water.
