I can speak from a player side for ya.
World - Dawnforge
Levels 14-16
Characters involved -
Morigath(Me) - Wizard
Didius - Sorceror/Wild Mage
Donnie - Fighter Cohort to Didius
Lots of other combatants and what not of the party and monsters.
Middle of Combat, I'm struck dead as a doornail.
Donnie yells back to Thorn-Disciple(think Cleric) and Didius. "Morigath is down and hurt bad." Donnie has no heal skills, he is a tank. Thorn can't get to him, so Didius being the Chaotic Wild Mage he is says "I wish Morigath felt better" thereby casting Limited Wish. Well since he didn't know I was dead, he figured it was the best wish he could come up with to get me back into the fight. So the DM rolls randomly between Reincarnate / Raise Dead / Revivify (Spell Compendium) and comes up with the Reincarnate.
Has Didius roll %% without telling him why, consults chart and now the Trueborn Human Wizard is the Dawnforge World's first Half-Elf. All and all it worked out great for me 'stat-wise'. I was playing a Middle-Age Character, and because of the race change it made me barely an Adult in Half-Elf years, and with Reincarnate you gain all the physical (Str/Dex/Con) properties of the new race but retain your mental (Int/Wis/Cha).
Notes for those that play Dawnforge.
After some talking with the DM, we went with that Half-Elves would be a mix of Dawn-Elves and Lowlander Humans. With this change to my PC, and the fact you can't unlearn things we went with the Racial Transformations were the only changes. So it has been interesting so far.
We have a 'tenative' theory of Talents coming from 'Mother Race' and Transformations coming from 'Father Race' but that is still somewhat up in the air.
And for those that 'repopulate' the chart, if we had done that with playable races I would have come out a Minotaur Wizard with none of the Mental Penalties for such.

But it did cross our mind for a half-a-sec.
