So why do you like to support the use of "failure prone" active PFC rather than tuned LC filters?

It's a line pollution control to clean up the pollution caused by highly polluting power electronics loads. LC filters are good. It would be the most effective combined with facility level electromechanical power conditioner.
I support NOT using full conversion POWER ELECTRONICS in the first place or a drive method using the integrated EMBEDDED SYSTEM design using locked-up away from tear-down firmware. Power electronics cause things to be fragile an unreliable especially when used for full conversion and try to run the show, but they're useful as a side show parts.
Many power electronics based solid state double conversion UPS have abysmal efficiency.
Here's one of the most resilient, durable and dependable design of line conditioner, power factor correction and harmonic mitigation and can be made to surpass the efficiency of power electronics based double conversion at larger sizes.
No adverse interaction with fuel driven generator. The power factor can be smoothly adjusted to leading or lagging by changing the field excitation level using limited amounts of power electronics or entirely analog embedded system free motorized variable auto transformer free design. NO HARMONICS.
