Background

#6215
This subitem is focused on code in src/Deprecated/*
Currently 11 usages. Hopefuly this doesn't need to be touched, or at worst just conditioned, otherwise cost might be significant

Expected output

Find answers to below questions (and if any work is recommended to be done - create item for next sprint):

• Are there any scenarios where code in src/Deprecated/* can be part of NET binaries (not FullFW)?
• Is it find to ceompletely left out this code from BinaryFormatter deprecation effort? Or do we need put usages behind explicit opt-in?
• Based on above findings - what is the suggested resolution for code in src/Deprecated/*?
