Option to respect colClasses data type specification i.e. no bumping. Any inconsistencies could be forced to NA and these problematic columns would be reported.

Often I get artefacts in second hand data which force a numeric to character bump which is not desired.

Recent changes might have already resolved some functionalities around colClasses.
Anyway bumping numeric to character does not happen without good reason, and I doubt colClasses should force numeric in such a case.
This issue is not well defined, @dwaggott could you please provide reproducible example?
