Short answer: No for new projects, but yes for legacy validation.
SAS 9.0 is two decades old and lacks support for:
However, regulated industries (especially pharma) still maintain validation lock-down environments where SAS 9.0 is frozen for re-running historical analyses. If you need to reproduce a 2005 clinical trial exactly, you must use SAS 9.0 – not 9.4, which may produce slightly different floating-point results in rare cases.
The pharma industry, a stalwart SAS user, immediately adopted 9.0 for:
Bureaus of Labor Statistics, Census, and Agriculture used SAS 9.0’s PROC SURVEY family to produce official reports with accurate standard errors from complex household surveys—something previous versions handled poorly.
