“Citation required.” 
Type 1 fonts are still supported on MacOS, and Apple has given no indication that they are deprecated. I can’t find anything to suggest that Windows is different in this regard, either.
Alternatively, you may want to check the licence of your font, as some foundries allow (or used to allow) the conversion of a font to a different format, as long as you’re not using both on different machines.
Never assume that everyone wants the same thing as you! I certainly prefer non-lining figures for verse numbers.
