Not true - I am looking into Bitwig as we speak because I could get it for 190€ right now and while it's a lil' convoluted, Bitwig's MIDI loop-recording is perfectly functional&useable.
You can record to a scene - this will get you one long recording which you can then drag on the timeline and split into takes and you subsequently can consolidate those takes you want to keep and finally drag these back into scene slots - that certainly does the trick.
Reason on the other hand simply has no such functionality at all. There's no workaround, using a footpedal to manually create a new lane aside.
