The engine shouldn't "lug".
Hard accel at low rpms produces more like a series of hammer bangs than
a series of smooth and closer together power strokes.
This banging is the enemy of crankshaft assemblies and bearings.
It can handle it here and there but repeated lugging will make some
very loose and loud clearances in the bottom end of the block. This begins
the slow chain reaction of cylinder wear due to crank to rod slop and will begin
to machine and consume the lower wear surfaces. It's a total no-no. A few thousandths
here and there will start the decline of the engine's service life way too soon and happen quicker.
I've done the slow cruise at 2800 rpms in lower gears around town,
but don't whack the throttle until the spin is well over 3,000.
Just did a lil' math.
At 4,200 rpms that's a quarter million revolutions per hour, and a million in only
4 hours of riding at 60 mph.
Countless millions of cycles with repeat even in a month. (let alone the lifetime of the bike)
I wouldn't want any slop down south during that process.
Offroading is different. We lug here and there to get out of a tight spot but this
is where the clutch comes in. Keep the revs up a bit unless necessary.
