OpenGL is thread-safe which is actually pretty annoying and expective. 

OpenGL traditionally uses the "Bind to Edit" model. An alternative is called "Direct State Access" (DSA).

Bind to Edit:
GLuint Texture(0);
glGenTextures(1, &Texture);
glBindTexture(GL_TEXTURE_2D, Texture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);

Depends on OpenGL
Doesn't distinguish OpenGL profiles
Doesn't support texture swizzle
Doesn't explicitly export texture target, no texture rectangle support
Doesn't support texture formats from others graphics APIs than OpenGL
Doesn't make it easy to load only a subset of layers
Doesn't store faces continuously in memory
No sparse storage
