Preferably reporting them as we go, but more importantly it may
mean deeper changes as some checks may not make sense anymore
once an error is encountered (the christmas tree syndrome in
security monitors, i.e. too many error reporting may obscure the
real root cause).

Very good ones :)

That will allow checks to depend on some previous ones.
