Texlive "just" packages what's there it can't mostly change the
package code so you need to report this upstream to Javier to fix in
babel. It probably should force that UTF-8 is in fact the file
encoding in force when reading the utf8 patterns.
(\usepackage[utf8]{luainputenc} turns _off_ luatex's utf8 support)

Incidentally do you have a good use case for using luainputenc
(especially with utf8 encoding) from time to time looked at whether to
integrate something like that into inputenc but there are some issues
(not least with hyphenation:-) and no obvious real use cases for new
documents.
