Why does the Table service not support certificate authentication?

[jonnyleigh]

Which service(blob, file, queue, table) does this issue concern?

Table

Which version of the SDK was used?

Latest

What's the PHP/OS version?

n/a

What problem was encountered?

I would like to use Certificate authentication for calls to the table service, same as I can for Blob
The readme says it is not supported - I would like to understand why and to know if there's a timeframe for it becoming supported.
Thanks.
