Could be a soultion but i feel the POT will lost his linearity response. well i think
Let's do some math
1/5 pot maximum position:
in theory, we should have 1/5 Vcc on the wiper = 1 Volt
voltage divider resistor are 10 and 40K
Voltage divider ratio is 10/50K
Using the 15K pull up....
(10//15)/40K
voltage divider ration is 6/46
Voltage on the wiper = 6/46 * 5 = 0.65 Volts
1/2 pot maximum position:
in theory, we should have 1/2 Vcc on the wiper = 2.5 Volt
voltage divider resistor are 25 AND 25k
Voltage divider ratio is 25/50K
Using the 15K pull up....
(25//15)/25K
voltage divider ration is 9.3/34.3
Voltage on the wiper = 9.3/34.3 * 5 = 1.36 volt
and so on. Unless your application can deal with that kind of un-linear curve, yes you can use it. I'm not a fan of it

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
