That could be possible but many people might not know that they would need to use that separate u/v/normal reorientation command in order to control the result that they were getting with flow, so that could potentially be more difficult to use.

Just in general with various commands I've tried to make directional things more controlled by selection actions - for example if you do a sweep with "auto place" mode for placing the profiles, the end of the curve that you click closest to when selecting the rail will be the one that is used to start the sweep.

So matching surface to surface by paying attention to the selection area would fit in pretty well with how some other things operate already.

Well, your target surface is flared out wide on one end near the bottom and compresses down near the top, so that's going to cause a kind of squishing distortion in the area near the top.

There isn't any way for the flow command itself to avoid that squishing - squishing things is basically fundamental to how it operates.

If you want a non-squished looking result you may want to try some other construction method like use just on a circle curve to place a path on to your target surface using Flow and then do a sweep of a circle along that path curve to make a more uniform tubular type shape result, rather than including the tubular surface directly with the flow which will squish it.
