+Out of the MISA discussion came a "MISA-like" proposal, which would
+take into account the flaws pointed out by trying to use "MISA":
+
+* The MISA-like CSR's meaning would be identified by compilers using the
+ mvendor-id/march-id tuple as a compiler target
+* Each custom-defined bit of the MISA-like CSR would (mutually-exclusively)
+ redirect binary encoding(s) to specific encodings
+* No Extension would *actually* be disabled: its internal state would
+ be left on (permanently) so that switching could be done inside
+ inner loops.
+
+Whilst it was the first "workable" solution it was also noted that the
+scheme is quite invasive: it requires an entirely new CSR to be added
+to the privileged spec. This does not completely fulfil the "minimum
+impact" requirement.
+
+Also interesting around the same time an additional discussion was
+raised that covered the *compiler* side of the same equation. This
+revolved around using mvendorid-marchid tuples at the compiler level,
+to be put into assembly output (by gcc), preserving the required
+*globally* unique identifying information for binutils to successfully
+turn the custom instruction into an actual binary-encoding (plus
+binary-encoding of the context-switching information). (**TBD, Jacob,
+separate page? review this para?**)
