No. We actually only have been adding standards compliance as a labour of love for retro-computing in the last few years. It is in a special mode though (-Miso and not complete, but every major version is slightly better).

Don't put the Pascal standards on the same pedestal as C or C++ standards, standards compliant Pascal never took off on PC and with the demise in 2010 of GCC derivate GPC, it is pretty dead. (and was already only limping before that).

File I/O is different between standards and borland. There are also more limitations of unions usage in standard pascal.

Unless you are specifically planning to target known Standard Pascal codebases, I would avoid that, and go for actually living dialects TP (procedural) and Delphi (more object oriented, includes nearly the entire TP dialect)
