Because:

1> the old regexpr.pas had something like 20 lines of code and it's
own description said it doesn't even support most POSIX, so it didn't
look very useful?
2> Most of Joost's code is in regex.pp which was not changed, not in
oldregexpr.pp
3> Compatibility with Delphi projects which use regexpr.pas where it
means Sorokin's RegExpr (I've already found a couple of those only in
projects which I develop, I don't know if it was included in Delphi,
but I think it is possible because I found some projects which use it
but don't have it in the sources)
4> Beginners would most likely try to use regexpr.pas which has the
most simple name, they are better off trying to use the Sorokin
version.
5> Benjamin Rosseax regexpr is a new invention, not something well
stablished and widely used like the Sorokin unit (even Lazarus uses
the Sorokin version), so I recommend naming it something like
benjaminregexpr or something like that.
