<br>
For those not actively following github tickets & PR, I just want to <br>
point to a new pending major functionality to improve management of <br>
virtual mosaics with a very large number of tiles/sources (> tens of <br>
thousands of tiles), by referencing them as features of a vector layer <br>
(typically created by gdaltindex), instead of a XML file as in <br>
traditional VRT, augmented with additional metadata.<br>
