One of the changes for MkIV was to make _, ^ and normal characters

doesn’t matter because has it’s normal meaning when you use
\unprotect … \protect but it can’t be used in the document.

Re: [NTG-context] halign broken
I see, it is either the nuisance of having to type \ etc. in the text, or the
nuisance of having to wrap everything like \halign in \unprotect..\protect and
then resorting to \ again.
At least there is nothing amiss with \halign itself, which is reassuring.
However, I do not feel secure with these little deviations from the orginal TeX.

Re: [NTG-context] halign broken
There seems to be more to it:
This works:
\unprotect\halign{\hfil\it#\hfil\hfil#\hfil#\hfil#\hfil\cr
ABCD\cr ABB\cr}\protect
But these generate a missing } after the \halign:
\unprotect\framed{\halign{\hfil\it#\hfil\hfil#\hfil#\hfil#\hfil\cr
ABCD\cr ABB\cr}}\protect
\framed{\unprotect\halign{\hfil\it#\hfil\hfil#\hfil#\hfil#\hfil\cr
ABCD\cr ABB\cr}\protect}
Is such a construction (now) impossible?

You can disable this with \donknuthmode at the begin of your document or

Thank you. I think that \halign, being a primitive of tex, should be
respected. If a user wants to use it, it should be usable
unconditionally.

I've no idea from where you came with this impression, is is usually the
other way around; people are advised not to use low level TeX code where
context has higher level interfaces, else you are on your own and should
be aware of the implications/side effects.
I, for one, grateful that I know longer need to escape regular
characters in my documents just to keep supporting some obscure TeX
feature.

in context a more abstract coding is advertised; if you want to use
halign in for instance a macro definition, you can surround it by
\unprotect
macro def
\protect
anyhow, when using halign directly in your document, don't expect too
much from spacing
