What's the point? Seems like pointless nostalgia. Cum hoc ergo propter hoc, indeed.
The numbers have become largely, or even completely, irrelevant. Even the FIA itself now includes the driver name in its Race Control Twitter Feed, or whatever name they have concocted. No longer do we see that 'car 8 is under investigation', for example. The large poles at tracks like Suzuka, the Nürburgring, Austin, Barcelona etc. all show the driver names rather than the numbers, too. The Live Timing still includes the number, but the name is often listed first.
The names are more human, and thus a great fit for the soap-opera elements of F1.
Compare: Did you know that driver 6 thinks driver 3 is better than driver 1? to ALONSO FAVOURED BY HIS PEERS. VETTEL STAYS SILENT - ENJOYING WEEK OFF AFTER CHAMPIONSHIP VICTORY.
The latter is clearly far better.
