[still working to somewhat reproduce my old mkii setup in LMTX]

The following is a minimal example that shows the following:
context test2.tex results in
The first line after the initials not as much indented as it should be
Character protrusion in a footnote does not work (see “refer-“ at the end of the 5th line of the footnote) (I understand the trouble on the first line
context --mode=OPTIMA test2.tex results in
The first line after the initials not as much indented as it should be
"because” is not hyphenated. Note, I see this is a smaller font setup where there is clearly an option to hyphenate, the minimum example shows the same effect, but potentially not from the same cause)
Character protrusion in a footnote does not work
context --mode=OPTIMANOVA test2.tex results in
The first line after the initials not as much indented as it should be
Multiple instances of extending beyond the right
Character protrusion in a footnote does not work
Adding \setupalign[hanging,hz] to the Optima Nova example results in ‘because’ on the first line to be hyphenated as ‘be-cause’ and pigeonhole in a later line as 'pi-geonhole'. 

I am adding a screen shot of part of the Optima Nova result as most will not have that font available:



- All show no protrusion in the footnotes
- All show a problem with the first line after the initial
- When using Optima Nova, hyphenation isn’t used while the situation in Optima looks nearly identical.

can trust me on that, or ask your engineers.}
