How does the recent phenomenon of "Bardcore" (modern songs remixed to sound like Medieval tavern music) compare to real music from that era?

by adavichel

Here are some examples of what I'm talking about:

Summertime Sadness - Hildegard von Blingin

House of the Rising Sun in Old French - the_miracle_aligner

Their styles seem to be fairly spread out from the early 1100s France to Tudor Britain so sorry in advance if that's too broad of a time range.

The sounds themselves are made by modern synths and software but if they were hypothetically created by the real instruments, could a person from this era be fooled into thinking the song is contemporary? Or are the musicians leaning too far into stereotypes?
