Fundamentally, this should not be i think
CCITT Rec. T.81 says
"If a table specification for a
given destination occurs more than once in the compressed image data, each specification shall replace the previous
specification. The quantization table specification shall not be altered between progressive DCT scans of a given
component."
This explicitly mentions quatization tables but not huffman tables so it
seems allowed that they can be changed

If you drop bombs on a foreign country and kill a hundred thousand
innocent people, expect your government to call the consequence
"unprovoked inhuman terrorist attacks" and use it to justify dropping
more bombs and killing more people. The technology changed, the idea is old.
