I don't think so. U just have to see which angle u are coming from.
For me kid beginners, or even other beginners, u can't know whether the interest remains. U based on your already know how to play like a pro will remain bias where people need to have weighted keys , etc. The only downside I see digital keyboards(DK) not being weighted.
Beginners I see what they learn is simple songs like London bridge and singing doremi. They are basically learning to recognize the keys and listen to play etc. That's what beginners are.

DK has come a long way and they now even have touch sensitivity. U can of course argue the feel is different but the goal here is to learn how to play. DK also I find it's more interesting to kids or beginners because it has many features than DP. It can keep the children remain interested than the old school piano / acoustic piano.

I think it depends on what u want. The old school way , the just learn to play and then when u want to fully focus on just acoustic piano they can switch.

With that I don't think it's a bad advise without giving any points on why it's bad besides the weighted keys or the so called feel which is subjective and debatable that I already know before deciding.
