No no no!
having to put a heat sink in is a game choice, just like shield booster, shield them selves (i don't use them in Pve combat). The argument of 'star to star, 'everyone has to do it', well lets get an opinion from someone that does that a lot jumps (total hyperspace distance 784,345);
At the start, when learning the limited set of skills of exploring, i used heat sinks a lot. i didn't slow down on entry or didn't wait until i was clear of the star before putting up my FSD charge. Flying into a start and having to exit/jump out men't i needed heat sinks (my own lack of skill).
Now i have some skill, i carry one heat sink , just in case.. when your 20,000 ly out in space, its worth having at least one. in local galactic space, there's little point, as any damage i may get isn't going to cripple me. not seeing heat damage being an issue in the bubble, unless you are relay inexperienced at jumps.
i fly into at least one or more tight start clusters when exploring, the worst case outcome, even for experience explorers, but yet to use a heat sink in that situation. So heat sinks are a tool for the inexperienced when it come to start travel. so my point is, they should not be included on the basis of, 'is absurd they would not be included when start are hot'
To me, this seems like a call for 'more space' from people that are not confident enough to go without a heat sink, but don't like giving up a slot. you don't need a heat sink for star travel, the ship has its own system of heat reduction that is turned off when in silent running. The heat sink is not an integral part of the ship, nor should it be.
Now if we looked at why some people relay want a stranded heat sink, i would guess its so they can happyly add all the other stuff they want, and have a heat sink to get away from unforeseen thermal attack, or coming back to the computer after they whent AFK just before a jump.
