BPM with 1 decimal instead of 2 in rekordbox

I've been reading a lot about this and many are complaining why Rekordbox (and other DJ software) use 2 decimals in the tempo instead of 1 like a CDJ2000. That it's hard to beatmatch using the tempo fader (on many DJ controllers) because it moves in such small increments like 120.54 BPM and not 120.5 BPM like a CDJ2000.

I've been DJ'ing with CDJ's for a long time now and only noticed this problem when DJ software came around. I'm a teacher and also sell Pioneer products as employee in a musicstore. For me it's hard to explain to students/customers why it's so hard to use the tempo fader to match BPM and they have to use the SYNC button, while on CDJ2000's this is very easy.
I have some knowledge on midi and basic programming, a simple quantizing (in the software) which divides the tempo fader in 0.1 secrements would do, this is a programming issue and should be easy to fix. I find it totally ridiculous it works like this in all software, there must something I don't understand since this is in most DJ software. Can someone explain this or is this problem just a reason for Pioneer to sell more expensive gear which doesn't have this problem?

Back in the days I've learned to DJ with vinyl, after that Denon and after that CDJ's, but this almost seems like a joke to me, everyone is complaining about this and people getting forced to use the SYNC button instead of the Tempo fader. Some say that the faders on a DDJ controllers are too short for this but if I'm correct it has 127 or 4096 like most midi controllers. which is plenty enough, this is a software issue not hardware.
