Rather, it’s because vV has already answered your question and there are other topics already dealing with this very thing.

In the topic above, look up “sample prehear”, and you will see 3 different topics already asking for this very feature…
I was only mentioned that speeeh’s topic was unanswered.
So it has been brought up before. Perhaps someone just could link to a previous topic at least. I’m sure both me and speech tried to search for a similar topic before starting up a new one. But sometimes it isn’t easy to find a previous topic handling the same feature, when every user obviously has their own definition and using different topic headlines of the feature in question. A feature which doesn’t even exist in the current version of Renoise to begin with. 
I was unable to locate any statement from the devs though, but I might have missed something. Perhaps some announcement like it will be brought back or not would be kind. But I’m not expecting any announcement, which was also part of my point in my previous reply here.
Regarding Vv’s reply it was a rather neutral statement that the feature was obviously removed.
Wouldn’t the global instrument transpose be easier to work with here?
Sorry, had to ask
It doesn’t work if the intention was just to playback the sample/selected area, it still play the sample in its original shape no matter what the global note of the instrument is.You still have to put it in the pattern editor and create a lot of empty patterns so it get some space to play it through… Unless you wanna hold down a key for several minutes that is. 
Anyway, in the other topics some other good arguments of the desired feature is presented.
