The tab is plastic, it can't do the same thing as the pbp.
I think this should be addressable though? You would do the best you can with passive cooling and manage the rest with clock throttling. With the PineTab you could even create a new back cover design to accommodate a larger heat-sink.
But it's not just heat either, they would then need to adjust the power circuitry as well, the PineTab already discharges whilst on a charger when the CPU is under full load. And the charging time is also awfully slow.

Well I think they are also risk-adverse. The A64 to Pine is now very well understood, so much so that when they released the PineTab early-adopter edition I basically knew there would be very little problems due to their good understanding from the PinePhone device.
