Been there done that with 8 feet high brambles. Glyphosate is no good on
brambles, it just makes them look poorly for a few weeks then they continue
growing with slightly deformed foliage. Even with repeat full strength doses
it survives. You have to use the strong weedkiller. Digging them up will not
succeed either as they will regrow from small missed bits of root.

That's overstating a bit. They'll grow from missed plant centres, even
if you've cut off all the top growth, but they won't grow from isolated
bits of root in the same way that, eg, bindweed would.
