Well, for it to have more significant digits would require somebody
to have been able to measure them. That again depends on somebody
having a reason to.
With the quality of current Rb based standards, I don't know if
there have been a method and motivation.
There is certainly nothing that mandates that it be an integer.

Never attribute to malice what can adequately be explained by incompetence.
