I visited his grave last year. It was packed with pilgrims.
It's surprising that they only waited 17 years to canonise him though.
Unusual, but not unprecedented in that he was so obviously a saint in his earthly life. I believe he was also known to many members of the Georgian Holy Synod, as well as His Holiness and Beatitude Ilia II, Catholicos and Patriarch of all Georgia. If I'm not mistaken, His Holiness and Beatitude's tenure has seen the glorification of more saints than at any other time (with the exception of large numbers of martyrs who didn't need formal glorification), particularly since 1991.
