I could see you not wanting your snake to ingest aspen (which can be avoided by changing substrate which is also mostly aesthetic), but everything else you mentioned is aesthetic. Owner benefit, meaning not having to clean.
Like I said, some people are fine doing this but there is reasoning behind why the majority of members on this site feed in enclosures. I am not going to say that anyone is a bad owner for choosing to feed outside the enclosure, and this subject has been discussed dozens of times on this forum.
In the end, yes it is personal choice, but the reasoning behind the better choice is clear.
