Why did Generalplan Ost differentiate between the Slavs?

What about Bulgaria and Croatia? They're Slavic nations too.

Well Bulgaria for example didn't even declared war on Soviet Union. However I didn't see any Nazi view on them.
Croats, I read somewhere were according to Nazis Croats were descendants of the Goths.

Bulgaria during the Second World War said:
“German propaganda had tried for a decade to undermine this sympathy for Russia, and on the eve of Operation Barbarossa Hitler had even suggested that Bulgaria should change from the Cyrillic to the Latin alphabet in order to lessen Russian influence. The Germans had also launched a minor propaganda campaign to convince the Bulgarians that they were not really Slavs and thus were not ethnically connected to the Russians. This theory was not without basis. The traditional view that a small group of Turkic warriors, the Bulgars, had been quickly submerged in a Slavic majority in the seventh century was not fully satisfactory. Moreover, since the date, the Slavic stock had been repeatedly diluted by mixing with other Balkan ethnic groups. Whatever may be the truth in this complex area, the Germans and pro-German writers went much too far in claiming that the invading Bulgars had destroyed almost all the Slavs inhabiting what is now Bulgaria.”

Of course if there's any rebellion in Bulgaria or any of the other allied states I expect harsh reprisals by the Reich against the relevant areas by simply wiping out entire villages or deporting them to be worked to death.

Well in Slovakia after Uprising was defeated most of the soldiers participating ended as regular POW. Leading generals were held and later disappeared at end of war in VIP KL. Most of the towns and villages from area were treated relatively OK however Germans and Slovak Hlinka Guard did burnt some and killed most of population. This happened mostly in areas with high partisan activity.

Interestingly some soldiers were released as POWs and allowed to return home. Some just returned home and were hiding with family or even managed to get paperwork straight out with help of friendly members of Hlinka Guard.

So at least in Slovakia Germans disn't burn everyting and killed everybody in areas where Uprising lasted for two months.
And to be fully honest. At least partisans committed some atrocities toward German civilians in area during Uprising.
