Every holster design involves compromises among the four factors of comfort, accessibility, security, and concealability.

IWB designs usually emphasize concealability, with some compromise of accessibility. Security is generally good because the bulk of the handgun is held closely into the body by belt tension.

The holster design you have described sounds like an attempt to increase accessibility. This may come with a compromise in security as the bulk of the handgun is not supported or secured by belt tension. Without some form of mechanical retention device such a holster would have relatively little retention ability.

Only the user can decide how much of one factor may be compromised in order to achieve the desired goals. Careful consideration and evaluation of one's usual activities are called for.
