Suggested change

is this maybe slightly cleaner regarding this context? 🤔

Suggested change
| return 1; | |
| return Number(samplingContext.parentSampled); |
!! otherwise this would propagate 1 for false :D

Should we backport this? 🤔 I think it may be worth it, makes docs much easier in that regard..? |

We found in getsentry/sentry-docs#12544 that the proposed ux is horrible because nobody would understand what it does, so we're adding a helper that facilitates inheriting a sampling decision that also allows for catching more edge-cases without worsening ux and is self explanatory in what it does.
