Of course, there's thin kerf, then there's REALLY thin kerf

10" Laser Kerf Saw Blade 40T, .063" Kerf With 5/8" Arbor-Carbide Router Bits | Router Bit Sets | Shaper Cutters | Saw Blades | Planer Knives | Jointer Knives | Infinity Cutting Tools

Been tempted to try one of these - might be a bit wibbly-wobbly even with the built-in stabiliser though

I do notice a big difference on my (underpowered) JET tablesaw when using thin-kerf blades. In fact, the standard kerf combo blade only gets an outing when everything else is off being sharpened.
