I don't remember whether late Research Unix had -if, but Plan 9 certainly
did.

Indeed, but no "dd" I know has "-if" etc; is that a Penguin thing?
Not a penguin thing on current xubuntu.
Never seen that either, POSIX doesn't suggest any support for that either,
with this in the RATIONALE section:
---QUOTE---
The OPTIONS section is listed as "None" because there are no options
recognized by historical dd utilities. Certainly, many of the operands
could have been designed to use the Utility Syntax Guidelines, which would
have resulted in the classic hyphenated option letters. In this version of
this volume of POSIX.1-2024, dd retains its curious JCL-like syntax due to
the large number of applications that depend on the historical
implementation.
