If this is not mere rhetoric, it is a slightly confused question.
Were Indo-European merely something that arose from convergence, then
the question would be, 'What can a date for PIE mean?'. A more
serious question would be, 'What does a date for PIE mean if
Indo-European expanded from a stable group of closely related
dialects?'. I suspect that a stable group of closely related dialects
would typically be glottochronologically dated as having diverged a
few hundred years ago. For examply, my idiolect seems to have
diverged from the idiolect of the Swadesh word lists about a century
ago. The answer would then be that the coherence of the PIE dialects
broke down a few centuries after the deduced divergence date.

However, absolute linguistic chronology is highly suspect.

These 'artificial provisions' might be akin to the identification of
Indo-European substrata in Greek. However, there would be a big
difference - these substrata would contain much of the core vocabulary.

Disentangling mixtures is nothing new - Armenian may well be the best
example. There are also Austronesian mixtures and Tai-Kadai mixtures.
The contributions are teased apart by noting their correspondence
patterns. (In the Tai-Kadai example, Laha, Ostapirat identified the
Tai loans by their tonal correspondences.)
